When you are talking in terms of reliable energy. Coal is still the cheapest and will be for a long time and won't be replaced anytime soon. In the media and online articles, most calculations of renewables such as solar and wind discounts the "reliability" aspect of energy production. As said earlier, in order to make renewables as reliable batteries are required. When you add the cost of wind or solar PLUS the cost of discharging and recharging of the batteries. Renewables are still more expensive than coal and will be for a long time to come. Yes, renewables have been taking a dent into coal profits, but I don't believe it is a much as people in the market expect.
